Ultrastructural Changes in Lung Allografts: Endothelial Changes Correlate with Donor Specific Antibody & Antibody Mediated Rejection
Introduction: Antibody mediated rejection (AMR) causes lung allograft (LA) injury. Challenges with C4d interpretation & lack of specific histological criteria account for difficulty in diagnosing…2018 American Transplant Congress
Performance of Molecular Diagnostic Algorithms of T-Cell Mediated Kidney Rejection (TCMR) in Non-Transplant Biopsies with Interstitial Nephritis
DNA microarray based tools for the diagnosis of TCMR have been developed and are now being offered commercially. There is need to further evaluate the…2018 American Transplant Congress
Increased Pre-Transplant Rejection-Risk Measured with Allospecific T-Cells Predicts Delayed Immunosuppression Minimization in Children with Intestine Transplantation.
Pediatric Abdominal Transplant, Children's Hospital of Pittsburgh of UPMC, Pittsburgh, PA.
BACKGROUND: Allospecific CD154+T-cytotoxic memory cells (CD154+TcM) are used clinically to predict acute cellular rejection (ACR) after intestine transplantation (ITx) in children <21 years old within…2018 American Transplant Congress
Treatment of Active Chronic Antibody-Mediated Rejection with Rituximab, IVIG and Plasma Exchange
Chronic antibody-mediated rejection (cABMR) and transplant glomerulopathy (TG) are main features associated with long-term graft loss. Despite its clinical significance, the available evidence on treatment…2018 American Transplant Congress
Preformed Donor-Reactive T-Cells That Persist after ABO Desensitization Independently Predict Severe Acute Cellular Rejection after Living Donor Kidney Transplantation
Donor-reactive T-cells have been suggested to impact allograft outcome due to a higher incidence of acute celluar rejection. These donor-reactive memory T-cells rapidly acquire effector…2018 American Transplant Congress
Discovery and Validation of a Urinary Exosome mRNA Signature for the Diagnosis of Human Kidney Transplant Rejection
1Transplantation Renal Center, BWH and BCH, Boston; 2Exosome Diagnostic Inc., Cambridge.
Kidney transplant rejection leads to short and long-term adverse clinical outcomes. Serum creatinine is a suboptimal late biomarker for rejection. Exosomes are nanometer-sized vesicles released…2018 American Transplant Congress
IgM HLA DSAs Do Not Alter the Outcomes of Renal Allograft Rejection
Introduction: whilst IgG HLA DSAs are associated with renal allograft rejection and graft loss, the role of IgM HLA DSAs is controversial. We investigate the…2018 American Transplant Congress
Eculizumab for the Treatment of Antibody Mediated Rejection in Kidney Transplant Recipients: A Single Center Experience
Pharmaceutical Services, UCSF Medical Center, San Francisco, CA.
BACKGROUND: Antibody mediated rejection (ABMR) accounts for 20-30% of acute rejection episodes and can affect long-term renal allograft survival. The complement system plays an active…2018 American Transplant Congress
ABO-Incompatibility Lower Incidence of DSA-Induced Antibody-Mediated Rejection
Introduction:Donor-specific anti-HLA antibody (DSA) and Anti-ABO antibody are major barriers for successful kidney transplantation. Limited data are available about the existences of both DSA and…2018 American Transplant Congress
Vendor-Specific Differences in Identical Strains of Mice Yield Dichotomous Result in Lung Allograft Rejection
Intro: Orthotropic transplantation of murine lung allografts has paved the way for mechanistic studies of pulmonary tolerance and rejection but discrepancies have been reported by…
